Topic: powerhouse 114 crankshaft (Read 4057 times)

Anybody out there running a powerhouse 114? If so what oil pressure do you see.I'm building an engine using one of their cranks and I know the standard type of Evolution oil pump won't work. They use 350 Chevy rod bearings that require more oil pressure.I've located a pump that I think will work but I need to do some modifications and I need to have new pump drive gears made.Is there anybody else trying to use one of these cranks?Thanks

I'm not running one of those, but as an engineer and car tinkerer from way back, if I were building one of those motors, I'd belt drive an external dry sump oil pumpsimilar to what they commonly use in sprint cars, etc. They're compact, modular unitsthat have ample volume and pressure. You can pretty much get one to matchany requirement you can think of.

In my opinion, the Harley arrangement is a bit fragile for supplying serious volume and pressure.

I,ve have only ever saw 1 once running,,,it just pulled in and was hot...It was running 40-50 psi,,When I saw it ,,,this motor was the new fresh "big deal" from Vern Ott,,you know babbit bearings,,offset Carrillo rods,,gerotor oil pump and a 7200 red line..I was impressed with the motor..Dave

Thanks for the responses.I didn't realize Vern Ott ran a gerotor pump.I found one that looks like it will work with some mods, It turns backwards from a standard pump. I'm pricing out gears to work with this combination.This one's not going to be cheap.Anybody else out there with any experience with these engines?Thanks guy's

The cranks are designed to fit big bore Evolution cases. The rods are side by side and have half the offset necessary to put the pistons back in linethe other half needs to be designed into the custom pistons, as I said this won't be cheap.The cranks are one piece and have a 4 inch stroke, I've heard they can spin to 9000 rpm.

They are still making these motors. Presently working on a shovel version. The cranks can also be had, brand new in whatever stroke length you'd like, although, I'm not sure you if you can order a crank sans the rest of the setup.

i live in md fella,s and i will say, that badas-- sleeper soon to hit the streets is the talk of the town around our little piece of dirt, i have followed it very closely and i,m here to say. its out there. for sure gonna be a contender. more than that i am uncomfortable with saying. it,s not a big secret, info is available on one of the primary forums. i just dont want to make a mistake and put biz on the street for whatever reason. i am not approved or qualified to speak for the company. but i swear, that motor is diff and bad to da bone period. it will also come with built in history because it is the result of many of the greats in our industry. now i ask you. how cool is that. pretty neat stuff i think. lupe

Its Dave at BMO that is doin the 114 shovel ,,he has bought the rights from Vern Ott...Dave also bought "Velva Touch " from Crane as they went down in quality from Vern's originals...I have dealt with Dave at BMO,,,good guy,,willing to help out...I would call him for parts on the 114,,,I imagine the bottom ends are almost the same from shovel to evo styles...Dave

My Cousin at Goblin Cycles in Geneva Ohio has featured those motors on a couple of custom bikes. I did some reading on them out of curiousity, from what I understand the oil pump was a feature on these bikes. It was my understanding that these oil pumps would generate constant oil pressure. He runs them hard and they make power 114 square motor.
